Question

Which statement(s) correctly compare the masses of protons, neutrons, and electrons? Check all that apply.

Answer 1

Protons and neutrons have similar mass.  TRUE

Protons and electrons have similar mass.  FALSE

Neutrons and electrons have similar mass.  FALSE

Protons are smaller than a neutron or an electron.  FALSE

Neutrons are smaller than a proton or an electron.  FALSE

Electrons are smaller than a proton or a neutron.  TRUE

Answer 2

An atom consists of two parts .In its nuclear part we will find neutrons and protons constituting the whole mass of the atom. Electrons are present in the extra nuclear part where they revolve around the nucleus in their respective orbits .

The rest mass of proton is $1.672*10^{-27} kg$.

The rest mass of neutron is $1.675*10^{-27} kg$

The rest mass of electron is $9.1*10^{-31} kg$

The mass of electron is 1/1837 times the mass of proton.

From above we see that protons and neutrons are comparatively same in mass.There is  a slight difference in their  masses which can be neglected.

Out of the seven options given in the question only the first and last options are right i.e protons and neutron have similar mass and electrons are smaller than a proton or a neutron.

The other options are completely wrong
